Polarstar Fusion Engine & F2 Nozzle/Poppet Spring - Light

This Light Spring replaces the Standard (Heavy) Spring which comes in the Fusion Engine and F2 HPA systems. The Light Spring is used to help equal the force balance to improve feeding and function when running the system in the lowest pressure range.

The PolarStar Light Poppet Spring is a direct replacement for the stock spring in the Fusion Engine and F2 systems. You can easily install it in a few minutes with basic tools.
The spring is also compatible with a variety of other PolarStar HPA systems, including the JACK and Kythera. This is also the "standard" spring that comes installed in the Kythera.
